Scandia partially stabilized zirconia (with 6 mol% Sc₂O₃) provides a good combination of mechanical strength and ionic conductivity.  ScSZ-6 is used as an electrolyte membrane for improving SOFC performance or reducing operating temperature; its higher mechanical strength enables membranes to be manufactured at lower thickness than ScSZ-10.  Its mechanical strength is equivalent to that of yttrium partially stabilized zirconia (YSZ-3) and its ionic conductivity is twice that of yttrium stabilized zirconia (YSZ-8).  The characteristics of this ScSZ-6 powder make it well suited for use in tape casting, ink formulation, pellet pressing and other ceramic manufacturing processes.
